Technical Field
[0001] This utility model relates to the field of PVC window and door technology, specifically to an intelligent PVC energy-saving and soundproof window and door structure. Background Technology
[0002] PVC windows and doors are a type of window and door made of composite materials of plastic and steel. They are mainly made of steel or steel core as the frame, combining the strength of steel with the corrosion resistance of plastic, and are widely used in residential and commercial buildings.
[0003] To overcome the aforementioned deficiencies, a prior art Chinese patent (publication number: CN211448323U) discloses a burglarproof PVC window and door, comprising a window frame, hinges, support rods, struts, a first glass, a second glass, a hinge shaft, a hinge frame, a pressure rod, a fixing plate, a lock block, a locking post, and a locking groove. The top of the inner wall of the window frame is fixedly connected to the top of the hinges. The right side of the first glass is fixedly connected to the front end of the support rod. The front end of the support rod is fixedly installed to the left side of the second glass. The front end of the hinge shaft is fixedly installed to the rear end of the support rod. The hinge shaft is fixedly connected to both ends of the hinge frame. By setting hinges, the first and second glass can be opened and closed with the window frame. By setting support rods fixedly connected to the window frame and hinge shafts fixedly installed to the support rods, the pressure rod and fixing plate are pushed to extend the hinge frame. By setting hinge shafts installed to the support rods, the hinge shafts and hinge frame can push the support rods out. By setting lock blocks movably connected to locking posts, the locking posts contact the locking grooves, thus achieving a telescopic mechanism composed of hinge shafts and hinge frames.
[0004] While existing technologies can overcome the shortcomings mentioned above, other problems still exist in their operation: traditional doors and windows rely heavily on manual operation for opening and closing, which is inconvenient and slow to respond to changes in the environment. Traditional doors and windows are generally supported by hinge structures, which may result in uneven stress distribution, leading to poor wind resistance. Utility Model Content
[0005] The purpose of this utility model is to provide an intelligent PVC energy-saving and silent door and window structure to solve the problems in the background art where the opening and closing of traditional doors and windows mostly rely on manual operation, which is inconvenient and slow to respond to environmental changes. Traditional doors and windows generally support the entire door and window through a hinge structure, which may have uneven stress and result in poor wind resistance.
[0006] To achieve the above objectives, this utility model provides the following technical solution: an intelligent PVC energy-saving and soundproof door and window structure, including an installation frame installed in the wall, wherein the installation frame is provided with three equally spaced partition frames, and the installation frame integrates a communication module and an electrical control module;
[0007] The mounting frame has three equidistant rotating frames hinged to its front side. The rotating frames and the mounting frame are hinged at their front sides by damping hinges. The rotating frames are rotatably connected to connecting rods on both sides of the end of the rotating frames away from the mounting frame.
[0008] Preferably, the connecting rod and the mounting frame are arranged in parallel, and the connection points of the rotating frame, the rotating rod, the mounting frame and the connecting rod form a parallelogram structure. The rotating frame is rotatably connected to the middle of both ends of the rotating frame.
[0009] Preferably, the end of the rotating rod away from the rotating frame is rotatably connected to a slide bar, and the slide bar is vertically slidably connected to the inside of both sides of the mounting frame. A sensor is provided in the middle of the front side of the rotating frame in the middle of the mounting frame, and the sensor contains a rear temperature sensor and a rain sensor.
[0010] Preferably, a rack is provided on one side of the slide bar, and gears are rotatably connected inside both sides of the mounting frame, with the gears and rack meshing with each other. The gears are connected inside the mounting frame via a rotating shaft, and a bevel tooth is fixedly connected to the end of the rotating shaft away from the mounting frame. Vertically distributed transmission rods are fixedly connected inside the mounting frame.
[0011] Preferably, the top of the transmission rod is equipped with bevel teeth, and the two bevel teeth mesh with each other. A motor is fixedly connected to the bottom of the mounting frame, and the output end of the motor is connected to the transmission rod.
[0012] Preferably, a fixed mesh is fixedly connected inside the partition frame, and the fixed mesh inside the partition frames at both ends of the mounting frame completely covers it. The fixed mesh inside the partition frame in the middle of the mounting frame covers the upper half of the partition frame, and a movable mesh is vertically slidably connected to the inside of the partition frame.
[0013] Preferably, a lock is installed on the inner bottom of the rotating frame in the middle of the mounting frame, and a lock groove corresponding to the lock is provided on the bottom inner side of the partition frame in the middle of the mounting frame. Two glass panes are fixedly connected inside the rotating frame, and the two glass panes form a cavity in the middle of the rotating frame.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] This intelligent, energy-saving, and soundproof PVC window and door structure converts rotational motion into vertical linear motion of the slide bar through a multi-stage bevel gear and rack and pinion mechanism. This motion drives the rotating frame to open or close. The rotating frame, rotating rod, mounting frame, and connecting rods form a parallelogram mechanism, ensuring synchronous and stable movement. Damping hinges and a multi-point rotating frame distribute the support pressure, effectively dispersing the force and improving the stability and service life of the mechanical structure.
[0016] The system integrates temperature and rain sensors to monitor environmental parameters in real time. When the temperature exceeds the set threshold or rainfall is detected, the sensor sends a signal to the electronic control module to drive the motor to close the doors and windows, achieving a fully automatic response. The intelligent sensing enables adaptive environmental adjustment, improving the intelligence level of the doors and windows and the user's comfort experience.
[0017] The installation frame integrates communication and electrical control modules, supporting wireless connections such as Wi-Fi and Bluetooth. Users can remotely control the opening and closing of doors and windows through a smart home platform or mobile APP. At the same time, the system supports manual switching, ensuring operation even in the event of network interruption or equipment failure, thus enhancing reliability. Remote control combined with weather forecast data enables intelligent prediction and automatic adjustment. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Example 1: Please refer to Figure 1 - Figure 6This utility model provides the following technical solution: an intelligent PVC energy-saving and silent door and window structure, including an installation frame 1 installed in the wall, three equally spaced partition frames 2 inside the installation frame 1, and a communication module and an electronic control module integrated inside the installation frame 1; three equally spaced rotating frames 3 are hinged to the front side of the installation frame 1, and a damping hinge 4 is provided at the hinge point between the rotating frames 3 and the front side of the installation frame 1; connecting rods 5 are rotatably connected to both sides of the end of the rotating frames 3 away from the installation frame 1; the connecting rods 5 and the installation frame 1 are parallel to each other, and the connection points of the rotating frames 3, rotating rods 6, installation frame 1 and connecting rods 5 form a parallelogram structure; rotating rods 6 are rotatably connected to the middle of both ends of the rotating frames 3; a slider 7 is rotatably connected to the end of the rotating rod 6 away from the rotating frames 3, and the slider 7 is vertically slidably connected to the inside of both sides of the installation frame 1; a sensor 8 is provided in the middle of the front side of the rotating frame 3 in the middle of the installation frame 1, and the sensor 8 integrates a rear temperature sensor and a rain sensor; a rack 9 is provided on one side of the slider 7; gears 10 are rotatably connected to the inside of both sides of the installation frame 1, and the gears Gear 10 and rack 9 mesh with each other. Gear 10 is connected to the inside of mounting frame 1 via a rotating shaft, and a bevel gear 11 is fixedly connected to the end of the rotating shaft away from mounting frame 1. Vertically distributed transmission rods 12 are fixedly connected inside mounting frame 1. Bevel gears 11 are installed on the top of transmission rods 12, and the two bevel gears 11 mesh with each other. Motor 13 is fixedly connected to the bottom of mounting frame 1, and the output end of motor 13 is connected to transmission rod 12. Fixed mesh 14 is fixedly connected inside partition frame 2 at both ends of mounting frame 1. The fixed mesh 14 completely covers it, and the fixed mesh 14 inside the partition frame 2 in the middle of the mounting frame 1 covers the upper half of the partition frame 2. The inner side of the partition frame 2 is vertically slidably connected to the moving mesh 15. The bottom inner side of the rotating frame 3 in the middle of the mounting frame 1 is equipped with a lock 17, and the bottom inner side of the partition frame 2 in the middle of the mounting frame 1 is provided with a lock groove 16 corresponding to the lock 17. Two glass 18s are fixedly connected inside the rotating frame 3, and the two glass 18s form a cavity in the middle of the rotating frame 3.
[0027] The automatic control of door and window opening and closing is achieved through the synergistic effect of mechanical transmission and intelligent sensing. When the motor 13 starts, the output end drives the vertically installed transmission rod 12 to rotate. The bevel tooth 11 at the top of the transmission rod 12 rotates accordingly and meshes with another bevel tooth 11 inside the side wall of the mounting frame 1, transmitting the rotational torque to the horizontal rotating shaft. This rotating shaft drives the gear 10 to rotate synchronously. Since the gear 10 and the rack 9 on the side of the slide bar 7 form a meshing pair, the rotational motion of the gear 10 is converted into the vertical linear motion of the rack 9, thereby driving the slide bar 7 to slide up and down in the guide rails on both sides of the mounting frame 1. The motion of the slide bar 7 is transmitted to the rotating frame 3 through the rotating rod 6. One end of the rotating rod 6 rotates and connects to the rotating frame 3. The first end is attached to the slider 7, and the second end is rotatably connected to the middle position of both ends of the rotating frame 3. When the slider 7 moves up, the rotating rod 6 pushes the rotating frame 3 to unfold outward; conversely, when the slider 7 moves down, the rotating frame 3 closes inward. The rotating frame 3, the rotating rod 6, the mounting frame 1, and the connecting rod 5 form a parallelogram mechanism. The front side of the rotating frame 3 is hinged to the mounting frame 1 through the damping hinge 4, and its two sides away from the hinge end are rotatably connected to the mounting frame 1 through the connecting rod 5. This structure ensures that the rotating frame 3 always moves synchronously during the opening and closing process, and the three rotating frames 3 are responsible for the opening and closing process of the same window, reducing the supporting pressure of the damping hinge 4 on the rotating frame 3 and extending its service life.
[0028] Sensor 8 is integrated on the front of the middle rotating frame 3 to monitor environmental parameters in real time. When the built-in temperature sensor detects that the indoor temperature exceeds the set threshold, or when the rain sensor senses precipitation, the signal is transmitted to the electronic control module in the mounting frame 1. The communication module converts the command into a drive signal for the motor 13, so that the three rotating frames 3 close or open synchronously to achieve a fully automated response. When closed, the lock 17 at the bottom of the middle rotating frame 3 is embedded in the lock groove 16 at the bottom of the corresponding partition frame 2 to form a mechanical lock.
[0029] The upper and lower separation frames 2 have fixed mesh 14 that completely covers the frame body, while the middle separation frame 2 has fixed mesh 14 covering the upper half and vertically sliding movable mesh 15 covering the lower half. When the rotating frame 3 is opened, the fixed mesh 14 and the manually adjustable movable mesh 15 together form an insect barrier. By opening the movable mesh 15, the lock 17 and the lock groove 16 can be manually pulled to lock each other. In addition, the separation frame 2 divides the inner side of the mounting frame 1 with smaller holes to prevent outsiders from entering the room through the mounting frame 1.
[0030] The mounting frame 1 integrates a communication module and an electrical control module. The communication module is mainly responsible for exchanging data with external devices or systems. It connects to the smart home platform or user's mobile APP via wireless networks such as Wi-Fi or Bluetooth to receive manual opening and closing commands, weather forecast data, or custom settings, and controls the windows according to local weather data. The electrical control module, as the central processing unit, is directly connected to the communication module. It is responsible for analyzing input signals, executing control logic, and driving actuators such as motor 13 to operate the opening and closing of doors and windows.
